Hi! Tried updating the firmware of my 5800XM but was always getting the error:

Software update Failed

For optimum connectivity, your USB cable should be connected directly to the PC, and not via a USB hub, USB keyboard or laptop station.

I already tried it in 2 other Desktop PCs and a laptop but I keep on getting this error…but the connection to PC Suite is working fine and without any problems…i also turned off windows firewall and does not have any 3td party firewall but still can't update...Appreciate all your help. Thanks!
